Management of cotton fields in the summer should focus on promoting the rapid development of cotton trees, stable scaffolding, health care, growth, growth, and strengthening of buds, prevention of droughts, floods, sudden changes, disaster prevention, and strain management, and should focus on the following key measures.
Remove the leaves from the cotton field as soon as possible to grab the sunny leaves to remove excess leaf buds. The leaves that you choose to stay must also fight at the right time. After the removal of leaf shoots, a 600-fold solution of new high-fat lipid film was applied to form a layer of polymer membrane, and the pathogen was infested from the wound.
The roots of loose soil should be loosened and weeded in time to remove soil compaction, improve soil permeability, promote root development of cotton seedlings, and accelerate the growth of cotton. To combine weeding with weeds, do a good job of rooting. To practise soil, do not use ploughs to plough and cultivate the soil, form high-quality cotton field strips, and increase cotton's ability to resist wind and lodging. To promote the elimination of cotton fields, it is necessary to select suitable drugs and regulate the use of drugs.
Scientifically regulating the timely application of Huahua No. 3 cotton topping agent during the flower bud differentiation period can force the nutrient backflow to the boll development and weaken the top advantage until the top stops growing, thus achieving the purpose of topping.
Post-disaster remediation storms caused the lodging of cotton, and it was necessary to timely support; heavy storms caused flooding of cotton fields and timely drainage and drainage; hail disasters damaged cotton seedlings, and should be promoted by the seedlings. In addition, the new high-fat film and cotton stilbine are sprayed. After treatment, plant nutrient digestion and metabolic energy increase, need to be timely fertilization and watering, in order to rapidly develop.
Prevent pests to correct insect-resistant cotton does not need to control the fuzzy understanding of pests, the blind stink bug, spider mite, aphid damage to the cotton field to timely spraying control, medication can be used together with the new high-fat membrane. Control the volatile and volatile pesticides, prevent the erosion of light rain, reduce the dosage per acre, and improve the control effect.
